What is continuous commissioning (CCx)?

• A. Owner continues to collect and compare baseline data on selected building systems to ensure that the building functions optimally throughout its operating life.
• B. A one-time validation of systems
• C. Focus on financial performance only
• D. Requires only a single annual check

Answer: (A)

Continuous commissioning is an ongoing process of monitoring and optimizing the performance of building systems after occupancy begins. It involves collecting baseline performance data for selected systems and continuously tracking actual performance so you can detect deviations, control faults, and aging effects as conditions change with occupancy, weather, and equipment life. The goal is to keep energy use, comfort, and reliability aligned with design intent throughout the building’s operating life, not just at turnover. This approach uses continuous data, trends, and periodic adjustments to controls, schedules, and setpoints to maintain optimal function over time. It isn’t limited to a one-time validation, a focus only on finances, or a single annual check.
